According to the research report titled, 'U.S. Water and Wastewater Treatment Technologies Market by Treatment Technologies Type (Membrane Separation & Filtration, Sludge Management Technology, Activated Sludge, Clarification), and Application (Municipal, Industrial) - Forecast to 2035,' the U.S. water and wastewater treatment technologies market is projected to reach $43.8 billion by 2035, at a CAGR of 6.4% during the forecast period 2025-2035. The report provides an in-depth analysis of the U.S. water and wastewater treatment technologies market, emphasizing the current market trends, market sizes, recent developments, and forecasts till 2035.

Following extensive secondary and primary research and an in-depth analysis of the market scenario, the report conducts the impact analysis of the key industry drivers, restraints, opportunities, and challenges. The growth of this market is driven by strict environmental regulations requiring better treatment capabilities, large federal and state infrastructure investment programs, expanding industrial sectors with specific water needs, and rising water scarcity that boosts demand for reuse technologies. Moreover, the increasing use of membrane technologies and energy-efficient treatment systems is expected to support the market's growth.

However, high capital costs and complex regulatory compliance can limit market growth to some degree. The need to manage treatment waste and upgrade old infrastructure also poses ongoing challenges for companies operating in this market.

The key players operating in the U.S. water and wastewater treatment technologies market are Veolia Environment S.A. (France), Xylem Inc. (USA), DuPont de Nemours, Inc. (USA), 3M Company (USA), Pentair plc (Ireland), Kurita Water Industries Ltd. (Japan), Bio-Microbics, Inc. (USA), Kuraray Co., Ltd. (Japan), Trojan Technologies Inc. (Canada), Ecolab, Inc. (USA), and GFL Environmental Inc. (Canada). Emerging technology providers gaining traction in the U.S. market are Gradiant Corporation (USA), Aquatech International LLC (USA), and IDE Technologies (Israel).

The U.S. water and wastewater treatment technologies market is segmented by treatment technologies type (membrane separation & filtration, sludge management technology, activated sludge, clarification, chlorination, industrial demineralization, membrane bioreactor, UV and ozone, dissolved air flotation, electrochemical scale treatment systems, electrochemical water treatment technology, and other treatment technologies) and application (municipal and industrial). The study also evaluates industry competitors and analyzes the market comprehensively.

Based on treatment technologies type, the membrane separation & filtration segment is projected to account for the largest market share in 2025. The dominance of this segment is primarily attributed to stringent regulatory requirements for emerging contaminants removal, growing semiconductor and data center applications requiring ultrapure water, and technological advances reducing energy consumption and improving membrane lifespan. Membrane separation technologies enable organizations to achieve superior water quality standards with greater precision and control.

Based on application, the industrial segment is expected to register the highest CAGR during the forecast period. This segment's growth is primarily driven by the rapid expansion of the semiconductor industry driven by CHIPS Act funding, explosive growth in AI data center cooling requirements, battery manufacturing expansion for electric vehicles, and increasing focus on water recycling and zero liquid discharge systems. Industrial applications require specialized treatment solutions to address specific contaminants and operational needs, driving demand for advanced treatment technologies.

Growing Advancements in Wastewater Treatment Technologies The U.S. water and wastewater treatment industry is growing rapidly due to changing regulations, industrial growth, and new technologies. Federal infrastructure investments of over $50 billion by 2032 are helping speed up the use of modern treatment technologies in both municipal and industrial areas. The implementation of stringent PFAS regulations are greatly affecting more than 5,000 water systems in the country, creating strong demand for treatment technologies that can effectively remove these long-lasting pollutants.

Strategic Developments and Market Positioning In May 2023, Xylem completed its acquisition of Evoqua Water Technologies in a stock deal worth approximately $7.5 billion, forming the largest pure-play water technology company in the world with combined revenue of approximately $7.3 billion. In January 2025, DuPont decided not to spin off its Water Solutions division, keeping the unit that generates about $1.5 billion in revenue. The company leads in reverse osmosis and ion exchange technologies, focusing on tackling PFAS treatment issues.
